I'm running NetBSD 1.0A on a Sun IPX with 32 MByte of RAM. I just
updated to the latest kernel tar-file (from May 13).

I've added the following lines to my kernel configuration file to get
floppy support:

fdc0	at mainbus0
fd*	at fdc0

When I try to boot the new kernel, it hangs after printing:

fdc0 at mainbus0 ioaddr 0xf7200000 Hmmm..  pri 11, softpri 4: chip 82077

If I remove the floppy lines from the kernel configuration file, I can
build a kernel which boots without any problems.

Any ideas about what the problem is?

For reference, here my complete kernel configuration file:
